Sample 1:

2002 manufacture date for all components.  “ACU I 01” marking on back could indicate it was for US Navy Assault Craft Unit 1.  This design was used by US Army Delta Force (CAG) in the mid 1990s (source: but  this particular vest was not since it lacks tape residue and would have been obsolete at the time of production.  Cordura material is non-standard ERDL-like woodland, similar to my 2002 dated Ranger Body Armor.

Reverse side of elastic cummerbund (facing the armor plate bag) has no velcro.  It is just cordura and is meant to hold vest together when worn like rubber band.
